SPECIFICATION forming part of I ettelfs1 Patent No2-730,281, dated June 9, 1903.

u Application illcd February 28,1902.` Serial No. 96,121. (No model.)

To @ZZ/whom it may concern: y

Beitknown thatLGEoEcE FEED MEIER, of Muscatine, in the county of Muscatine and State of Iowa, have invented certain new and useful improvements in Adding-Machines;

and I ,hereby declare that the following is full, clear, and exact description thereof, reference being had tothe accompanying drawings, which form part of this specification.

This invention is Van improvement in calculating-machines particularly designed for use in adding numbers; and its object is'to pro-l duce a compact, efiicient, and reliable machine of this character.

The invention consists in the novel combinations and constructions of parts hereinafter claimed, and the accompanying drawings' illustrate a machine embodying the several features of the invention in the best formnow known to me and which I shall herein-v chine, so as to vary the appearance thereof and its parts, while retaining many or all of the essential characteristics of the invention as covered in some one or more ofthe claims. The invention comprises, 4 first, a novel means of supporting theregistering-disks and for throwing any of such ,disks into or out of` operative position; second, novelmeans forl imparting rotative movements to such disks; third, novel means for preventing backlashV of the actuating mechanism; fourth, novel;

carry-over mechanism; lifth, novel means for resetting the carrying-over devices; sixth, novel means for resetting the disks to zero position, and, seventh, novel combinations of such mechanisms.

In the drawings, which illustrate the best form of machine now known to me, but which is n ot the nal or only embodiment of the invention, Figure l represents al front view of the complete machine. Fig. 2 is a longitudinal vertical section thereot with casing removed looking from the left-hand side of the machine. Fig. 3 is an enlarged reverse section taken from the right-hand side of the machine. Fig. e is a top plan view of complete machine with cover removed. Fig. 5 is an enlarged rear elevation of a set of registering-disks and connections. Fig. 6 is an enlarged longitudinal section through a set of registering-disks and their connections. Fig. 7 is a detail view of the disk-setting-lever catch. Fig. 8 is a side elevation of the device with cover removed, showing the diskrotating mechanism. Fig. 9 is a detail view of parts of such mechanism. Fig. l0 is a sectional view on line 10 lO, Fig. 8. Fig. ll is a detail view illustrating part of the devices for releasing the locking-lever H. Fig. l2 is a detail view of the stop devices for shaft h. Fig. 13 is a detail view of the connection between shaft F and bar K.

Any desired number of registeringdisks A are arranged in axial alinement in the usual manner, six being'indicated in the drawings.

Each disk is loosely and independently journaled on a horizontal sleeve B', attached to a short standard B, these standards being fixed to a horizontal'bar Z', secured in the main frameZ. The disks are kept from longitudinal movement on sleeveB by any suitable means.y For example, fingers B2 may be attached to standards B beside the disks and engage annular grooves A in the hubs of the disks, as shown. Each disk A (except the right hand or unitsdisk) is provided on its left face with ten pins'A2, which are used in carrying over operations. To prevent backward rotation of the disks, dogs C .are pivoted on brackets B and engage these pins A2, being thrown int-o engaging position by springs C', as indicated in Fig. 2.

Extending axially through the series of disks A and the sleeve B is a rotatable shaft b, on which beside each disk A (except the last or left-hand disk) is splined a clutch a, having a pin 0, adapted to engage with one of a series of ten holes A8 in a'disk or flange A13 on the hub of the opposed adjoining disk A when the clutch is moved thereagainst. Each clutch ct is controlled by a clutch-lever a3, pivoted at its lower end on bar Z, as shown at a4, while its upper end engages an annular groove d2 in the hubof the clutch. The clutchlever has a laterally-projecting stud a5, which enters a hole D3 in the adjoining related setting-lever D, which is pivotedon a shaft or rod D', attached just above bar Z'. (See Fig. 2.) These levers extend forward and out of the casing, passing through a slotted front IOO bar Z2 thereof. Each lever is normally uplifted by a spring D2, connected to an overlying rod D3, secured in the frame, and the related clutch a is held out of engagement with the related disk A so long as the lever D remains in uplifted position. When a lever D is depressed, it rocks the connected clutch-lever a3, throwing its clutch a into engagement with related disk A, and the latter can then be actuated by rotating the shaft huntil the clutch is released. The lever D is held down when depressed by means of a catch-plate d, which is attached to the plate Z2 by means of screws d engaging slots cl2 (see Fig. 7) in plate d. Plate d has a vertical slot d4 for each lever D, slots d4 registering with the guide-slots Z3 in plate Z2, and at one side of each slot d is a catch d3. When any lever D is depressed, it engages 'the beveled mouth of the related slot in plate (Z and forces the plate slightly to one side until the lever passes below catch d3, when the plate d is thrown forward by a spring d5, as shown, causing catch d3 to engage the upper side of lever D and hold it down, thus bringing it-s related disk into operative condition. When any other lever is depressed, the plate d will be first forced back, so as to release the first depressed lever, which is immediately raised out of its slot d4 by its spring, while the second depressed lever is caught and held down. Thus any lever D may be depressed and locked down; but any previously-depressed lever will be simultaneously released. The last or left-hand lever DG, carrying the key marked O in the drawings, I use only as a setting device, and the slot d4 in plate d, which is engaged by this setting-lever D, has no catch d3, so that by depressing key O any previously depressed and locked lever D will be released and all the disks be freed from their clutches. The lever D is pivoted on a stud CZ? in rear of bar Z', as shown in Fig.` 3.

Each lever D carries a key, which are numbered l, 2, 3, 4, 5, and from right to left, l being the units-key, 2 the tens-key, and so on, the O key being the setting-key, as above stated. Only that disk whose corresponding key is depressed will be brought into operation. ln adding n nits key l will be depressed and remain down until the addition of units is completed, To add hundreds, key 3 will be depressed and held down until the addition is completed in like manner. Only the key for the denomination being added will be depressed. These keys l to do not Cause the turning of the disks, but only control their operative or inoperative condition. The rotation of any disk which is brought into voperative position is effected as follows:

On oneend of shaft b is a small pinion Z7', which meshes with a gear E, journaled in a `bushing EG, attached to the side of the frame toothed rack E is arranged opposite the gear E, said rack having a horizontal slot E2, by which it is supported and guided on a pin e9 on a slide c, having slots e', engaged by pins e2, attached to the frame Z. The rack also has inclined slots E3, engaged by pins e4, on a plate es, lying against slide e, pins e4passing through vertical slots e5 in slide e and being headed on their inner ends, so as to hold the rack and plate to the slide. The movement of the slide e should be retarded by any suitable means, (a frictionally-acting spring e6 being shown for that purpose,) so that plate e3 will move to the extent permitted by slots e5 before the slide will move, so that the rackplate e will be thrown outwardly into engagement With the teeth of gear E before it is lowered with slide e and will be retracted out of mesh with gear E before it can ascend with the slide. The slide e, plate, and rack are reciprocated vertically by means of a lever F', Fig. 8, attached at its rear end to a rockshaft F, journaled in the main frame and connected at its front end by a link F2 to plate e3, as shown in Fig. 8. Shaft F is returned by a spring, so as to normally raise lever F and hold slide ein uppermost position. A spring F4, attached to an arm F3 on the shaft and to a stationary cross-bar F5 in the frame, is shown for this purpose.

The adding-lever connections-The adding-key leverfis connected to shaft F to rock the saine and cause it to depress slide e. The rear end of lever j' is bifurcated and embraces a double-pointed pin FG, (see Fig. 2,) transfixing the shaft F at center, the bifurcation of leverf being provided with adjustable bearing-screws f', supporting the lever on the pin. This construction enables the leverf to swing laterally and horizontally on the shaft, while any vertical oscillation of the free end of lever will rock the shaft F. Leverfextends forward and outof the front of the casing through a suitable opening e' therein, below which opening are a series of nine vertical slots e', with either of which the lever may be engaged by first moving it horizontally in opening ,e until it comes over the proper slot and then depressing it vertically into the slot. To facilitate the entrance of the lever into the slots, their upper ends are widened, as shown. On the front of casing above the slots z' are index-numerals l to 9, inclusive, l being over the shallowest slot and 9 over the deepest. These slots are so proportioned in depth that if 1e. ver j' be depressed into the l slot the rack E' (through the described connections) will actuate gear E sufficiently to cause it to rotate shaft b one-tenth of a revolution, while if leverf be depressed into the 9 slot shaft D' will be rotated nine-tenths of a revolution. Within the casing and extending across the lower ends of slot e' is a barG, (see Fig. 11,) which has vertical slots G' in its ends, engaging guide-pins G2, attached to the casing. To this bar are pivoted at g two equal-armed IOO IIO

levers g, the inner ends of which are slidably connected by a pin g2 and slot g3, their outer ends being slotted at g4 and sliding upon pins G2. The inner end of one of the levers is connected by a lifting-spring g5 with the casing, the combination resulting in keeping the bar G normally raised above the lower ends of slots a, so that it can be depressed by lever f in any slot 5' and further causing bar G to descend bodily and equally when depressed'loy lever f. One end of bar G engages a crank G8 on a rock-shaft G4, that eX- tends back to and below gear E and on its rear end has an arm G6 mounted thereon and held up to its work bya spring G8, as shown. Arm G6 is provided with a tooth G7, that projects through an opening in the side frame over a locking-lever H, whichis pivoted to the frame below gear E and is provided with teeth H' on its free end adapted to engage the teeth of gear E and lock the latter, a spring H2 being provided to throw the lever into engagement with the gear when permitted by dog G7, which normally projects into the path of the lever and prevents the spring lifting it. The lever H has a short arm h, which is engaged by an arm F7 on shaft F when lever F rises and rocks lever H, so as to disengage it from the gear E and hold it disengaged until the adding-leverfis depressed. Arm F7 then releases lever l-I; but dog G7 still holds it out of engagement with gear E until bar G is depressed by lever f, thereby rocking shaft G4 and causing dog G7 to release lever I-I, which immediately locks wheel E and prevents momentum throw or backlash thereof, thus insuring accuracy of register. WVhen leverf is raised, arm F7, engaging arm h, disengages lock H from gear E and permits dog G7 to lock it, as before, until leverfis again fully depressed into some one of the slots z. To insure that clutches a will be .in proper position to engage with their respective disks A when moved toward them and to hold shaft b stationary during lateral motions of lever f, a disk b3 is fixed to the left-hand end of shaft b, said disk having ten pins b4, between any two of which a pointed tooth h5 on an arm 216, attached to the rock-shaft F, will engage when lever-fis in raised position. The tooth D7 is disengaged from disk b3 just as rack E engages gear E, and as the latter disengages gear E tooth h5 engages disk b3, so that the shaft b is always under positive control and irregular movements thereof prevented.

From the foregoing description it will be seen that the operator can bring any of the registering-disks l to 5 into operation by depressing the proper lever D, which causes the locking of such disk to shaft Z). Then by vertically vibrating leverf he can rotate shaft b andthedisklockedthereto. Each timeleverf is depressed into slot z' shaft F is rocked and gear E is rotated more or less. The full depression of lever f causes dog G4 to release lock H, which is thrown up into engagement with gear e by spring H2 and locks shaft l) until lever f rises and shaft F returns to almost normal position, when arm F7 engages arm h and throws the lock out of mesh with gear E and dog Gi springs out and holds the lock down until lever f is again fully depressed.

The carry-over mechfmism-1n order to effect the carrying over from a disk of lower denomination to the disk of next higher denomination when the former has made or makes a complete revolution, the following mechanism is used: On a transverse shaft I in rear of the disks are supported short sleeves I', each having two arms i and I2. Five of such sleeves are shown, one for each pair of disks. (See Figs. 2, 3, and 4.) The arm 12 projects beside the face of the disk of the lower denomination, and the arm i projects over and beside the adjoining disk of the next higher denomination. A spring I3 is coiled around the sleeve, one end being fast to rod F5 and the other end being fast to arm t', so that said spring tends to rotate the sleeve and depress the arms. The arms are, however, normally upheld by means of a catch-lever I4, which is pivoted on bar Z beside the disk and is held in position to engage arm I2 by a spring 1G. Said catch has a projecting beveled nose l5, which is adapted to be struck by an elongated pin A20 on the carrying-disk when the latter makes a complete revolution, saidpin forcing catch I4 back, and thereby disengaging it from arm I2 and permitting the spring I to throw the arm l2 down. The arm c' carries a dog i', which when the arm is depressed engages one of the pins A2 of the adjoining disk A and moves the latter one notch. The armll has a nose i3, which will engage the pins A2 and prevent dog t" rotating the disk more than one tooth or notch at a time. Dog z" is yieldingly heldin operative position by a spring t2. (See Figs. 2 and 3.) Thus each time catch I4 releases arm 12 the adjoining registering-disk is moved onenotch. The carry-over arms 12z` are reset after each operation by the following means: Suspended from each arm 12 is a link J, which is hung on apin J, attached to arm 12 and provided with a flat friction-spring J2, engaging the head of the pin J to prevent idle oscillations of the link. Thelowerend oflinkJdepends through a slot 7c in a transverse bar K, which is attached to arms K', loosely hung on shaft F and adapted to rest upon pins K2, attached to the sides of the frame. A spring K3 is attached to each arm K and the frame to hold the arms down on the pins. The bar K is, however, normally uplifted by means of arms F7, attached to shaft F and underlying bar K, the latter being provided with adjustingscrews K4 to contact with said arms F7, and when shaft F is in normal position (with lever fraised) bar K will be uplifted by arms F7. The lower ends of links J are notched to engage the bar K when moved forward; but they will pass idly through the slots unless pulled forward. To positively shift the arms J in engaging position, an oscillating lever j ICO TIO

is pivoted beside each catch I2 (see Figs. 2 and 5) in position to have its upper edge j engaged by the carry-over pin A00 after the latter has forced the catch-lever Il to release the arm I2. The lower end of leverjl depends below bar K and is'bent rearwardly and partly behind the lower end of the adjoining link J, as shown in Fig. 2, so that when the upper end of lever j is forced outwardly its lower end will be moved inwardly and swing the lower end of link J into engagement with the bar K, so that when said bar rises it will lift link J and arms I2 and t' until catch I4 engages and locks arm l2. The upper end of lever j is normally forced inwardly by spring jl. Links .I may also be pulled forward by springs J4, connected thereto by short links J5. The levers D, however, are provided with horns D7, which engage the upper ends of the springs and force them backward when the lever D is in uplifted position, as in Fig. 2; but when lthe lever is depressed springs J4 come into action.

The setting-Zercr.-'I`l1e setting-lever D0 is employed whenever it is desired to recommence any adding operations or to set the disks at zero. Above the series of disks A is a corresponding series of friction-disks L, (see Figs. 2 and 3,) mounted upon a common shaft L', which is loosely journaled in arms L2, attached to a rock-shaft L4, springs L5 being arranged to hold the shaft L' down yieldingly in its bearings. One of the arms L2 is connected by a link L5 to the lever D0, so that when said lever is depressed friction-disks L will be brought into contact with the registering-disks A. Shaft L' may be rotated by a hand-piece L0 on one end. In order to disengage dogs C from the registering-disks to permit their resetting, a bar M is suspended by links h from arms L2, said bar extending beneath the tails (l2 of the dogs and being provided with loops M2, adapted to engage the tails of the dogs when the bar M is depressed and throw the dogs out of position to lock disks A. In order to prevent any of the arms t' interfering with the resetting of the disks in case any of these arms should happen to be in depressed position, a lifting-bar N is arranged beneath the series of arms I2 and normally lies in a non-interfering position, being supported on the rear ends of rocking levers N', fulcrumed on pins n, attached to the side frames. The forward d ends of levers N' are pivotally connected to links M', so that when bar M is depressed bar N will be raised and will lift any arm I2 which might be depressed into engagement with its catch I4, at the same time raising arms t', so as to lift their noses 'i3 out of the way of the pins on the registering-disks. Further, to prevent the dogs z" interfering with the backward rotation of the disks A during the resetting operation the dogs t" are provided with horns i4, which will be engaged by shaft L' when the latter is depressed, and thereby throw the dogs t" out of the way of the pins on the registering-disks. Thus upon the depression of lever D0 the dogs C, arms t', and dogs z" are all thrown out of position to engage the disks A, while the frictiondisks L are brought into contact with the disks A, and by rotating disks L, so as to turn the registering-disks backward, the latter can be brought up to Zero position, being stopped at such position by pins A20, engaging the heads of latches I4. The highest left-hand disk A need have but the carry-over pin A20, and is so shown, and therefore no dog C is shown in connection therewith. Instead a friction-spring A0 is arranged to bear thereagainst with suihcient pressure to prevent casual rotation thereof.

Operation.-The disks A being set at zero, the operator wishing to add a column of figures must first depress the units -lever D (marked 1in the drawings) and then depresses leverf at the proper notch for each numeral in the units-column. He then depresses the tens-key, (marked 2 in the drawings,) which causes the release of the units-lever, and proceeds to depress lever j" in the proper notch for each numeral in the tens-column. In like manner he successively adds up the hundreds, thousands, dac., until the addition is complete, it being observed that in this machine only one denomination is added at one time, and care should be taken that no two levers D are simultaneously depressed or down during adding operations. The total sum of the additions can be read at any time at the sight-openings. When one sum is completed and it is desired to reset the machine, lever D0 (marked O in the drawings) is depressed, which releases all the registeringdisks, as above described, and enables them to be speedily turned to zero position by properly turning shaft L'. When no levers D are depressed, the registeringdisks remain free of shaft l) and will not be affected by the depression of the addinglever f.

The subsidiary operations of the several mechanisms are fully set forth in the preceding specific descriptions of such devices, and it is unnecessary to repeat the same here.

I do not restrict myself to the specific constructions of parts shown and described nor to the specific combinations of parts so coustructed except where particularly mentioned in the claims, for a skilled mechanic can simplify or change the appearance of parts without altering their essential functions or mode of operation, and therefore I refer to the following claims, rather than to the preceding description, for summaries of the features and combinations for which I desire protection.
